Synergy of TL1A and IL-18 promotes GM-CSF-dependent thymic granulopoiesis in mice

Background Introduction In acute systemic inflammatory conditions, the immune system undergoes significant changes, typically characterized by increased myeloid cell generation and suppressed lymphocyte production. In the thymus specifically, systemic inflammation leads to acute thymic atrophy and subsequent impairment of T lymphocyte generation. H...

HIF-1α and MIF Enhance Neutrophil-Driven Type 3 Immunity and Chondrogenesis in a Murine Spondyloarthritis Model

Research Background and Research Questions Spondyloarthritis (SpA) is a typical disease characterized by type 3 immune-driven inflammation and new bone formation (NBF). Although previous studies have shown that Macrophage Migration Inhibitory Factor (MIF) plays a key role in the pathogenesis of SpA, its interactions with other molecules and specifi...

Distinct Palmitoylation of FoxP3 Regulates the Function of Regulatory T Cells via Palmitoyltransferases

Unique Foxp3 Palmitoylation Regulates Tregs Function through Palmitoyltransferases Regulatory T cells (Tregs) play a crucial role in maintaining immune homeostasis and preventing excessive immune responses. As important suppressors of immune reactions, Tregs help maintain immune tolerance, thereby preventing autoimmune diseases. However, in the tum...

Neutrophil-Macrophage Communication via Extracellular Vesicle Transfer Promotes Itaconate Accumulation and Ameliorates Cytokine Storm Syndrome

This report is based on the following research article: “neutrophil–macrophage communication via extracellular vesicle transfer promotes itaconate accumulation and ameliorates cytokine storm syndrome”, written by Haixia Kang, Ting Liu, Yuanyuan Wang, Wenjuan Bai, Yan Luo, and Jing Wang, published in the journal “Cellular & Molecular Immunology” in ...

Eomesodermin spatiotemporally orchestrates the early and late stages of NK cell development by targeting Klf2 and T-bet

Spatiotemporal Regulation of KLF2 and T-bet by Eomesodermin During NK Cell Development I. Research Background Natural Killer (NK) cells are important cells in the immune system, capable of recognizing and killing tumor cells and pathogen-infected cells. The generation and development of NK cells depend on the gradual acquisition of a series of spec...

GITR Exacerbates Lysophosphatidylcholine-induced Macrophage Pyroptosis in Sepsis via Posttranslational Regulation of NLRP3

Research Background Sepsis is a life-threatening organ dysfunction syndrome caused by the body’s abnormal response to microbial infection. It has high morbidity and mortality, mainly due to excessive inflammatory response and metabolic disorders. Studies have shown that myeloid cells (such as monocytes and macrophages) play a key role in the pathog...

The Protective Roles of Integrin α4β7 and Amphiregulin-Expressing Innate Lymphoid Cells in Lupus Nephritis

Scientific Research Report: The Protective Role of Integrin α4β7 and Type 2 Innate Lymphoid Cells in Nephritis In a recent study, an international research team led by Dr. Seungwon Ryu revealed the critical protective role of integrin α4β7 and Type 2 Innate Lymphoid Cells (ILC2s) in nephritis caused by Systemic Lupus Erythematosus (SLE). The study ...

Targeting STING in Dendritic Cells Alleviates Psoriatic Inflammation by Suppressing IL-17A Production

Targeting STING in Dendritic Cells Alleviates Psoriatic Inflammation Psoriasis is a common chronic inflammatory skin disease primarily caused by abnormal activation of dendritic cells (DCs) and T cells, ultimately leading to increased cytokines such as interleukin (IL)-23 and IL-17A. The cGAS-STING pathway is known to play a key role in psoriatic i...

Neutrophils Disrupt B-1a Cell Homeostasis by Targeting Siglec-G to Exacerbate Sepsis

Research Report: Neutrophils Disrupt B-1a Cell Homeostasis by Targeting Siglec-G, Exacerbating Sepsis Background Sepsis is a life-threatening organ dysfunction caused by a dysregulated immune response to infection. The immune system dysfunction accompanying sepsis is primarily triggered by pathogen-associated molecular patterns (PAMPs) and damage-a...

Redefining the ontogeny of hyalocytes as yolk sac-derived tissue-resident macrophages of the vitreous body

The purpose of this paper is to explore the developmental origin, biological characteristics, and association with eye diseases of tissue-resident macrophages in the field of ophthalmology—hyalocytes. The eye is a highly specialized sensory organ that contains the retina, part of the central nervous system, as well as non-neuronal parts like the tr...
